North Carolina athletic director Bubba Cunningham says the school is gathering information on potential improper conduct by members of the men's basketball team a month after the drug arrest of leading scorer P.J. Hairston.

Cunningham's statement Wednesday didn't name any player specifically. He says he and coach Roy Williams "will support the appropriate disciplinary measures" for any player if warranted at the completion of the university's investigation.

The school started gathering information after Hairston was arrested in June during a license checkpoint and charged with misdemeanor marijuana possession. He was driving a rented vehicle linked to a convicted felon facing pending drug charges. Hairston is scheduled for an August court hearing.

Cunningham says the school is working to "bring these matters to resolution as soon as possible."
